Voronezh Nuclear Heating Plant, Unfinished nuclear heating plant in Shilovo, Russia.

The Voronezh Nuclear Heating Plant (Voronezhskaya AST) was designed as a nuclear heating station with two AST-500 reactor units, each with a thermal capacity of 430 Gcal/h, to supply year-round district heating to Voronezh. Construction began in 1983 on the right bank of the Voronezh Reservoir, about 6.5 km south of the city, on the site of the former village of Shilovo. The project was halted in 1990 and the structures were dismantled between 2020 and 2022.

Construction started in 1983 during the Soviet era when the government planned to supply the city with nuclear district heating. The project halted in 1990 after local residents voted against this heating approach in a referendum.

The site's name survives in Shilovo, the settlement founded in 1983 for plant builders about four kilometres from the old village of the same name, which was cleared in 1976. In 2013 enthusiasts proposed turning the unfinished building into a museum, and the regional government later studied a cultural centre before wear ruled it out.

The structures were dismantled between 2020 and 2022, with the process completed on 25 May 2022, so there is no building left to view; the site is a fenced, guarded plot managed by the Rosatom branch "Directorate of the Voronezh AST under Construction" with 28 staff. The plot lies about 6.5 km south of Voronezh on the right bank of the Voronezh reservoir, near the present Shilovo settlement founded in 1983 for plant workers.

The AST-500 reactor features 121 fuel assemblies made of zirconium-based alloy, utilizing an integral water-cooled and moderated system design.
